bitshift

Purpose

Shift an integer by a number of bits.

Synopsis

function bitshift(i:integer, n:integer):integer

Arguments

i	Integer to be shifted
n	Number of bits: >0 for shifting to the left and <0 for shifting to the right

Return value

Shifted integer.

Example

In the following, i takes the value 160, j takes the value 32, and k takes the value 1:

i:= bitshift(5, 5)
j:= bitshit(1, 5)
k:= bitshit(128, -7)

Further information

Shifting of 1 bit to the right is the same as dividing it by 2 and shifting of 1 bit to the left is the same as multiplying by 2.
